Recently we were fortunate enough to acquire a 2010 Honda CR-Z for development.

Our first impression of this little black specimen was a good one. The car is well sorted and comes with a bunch of cool little bells and whistles, such as interactive fluorescent gauges (The speedometer is peering through a magnified monocle which appears to hover mysteriously over the digital readout), a great stereo/bluetooth/media player, all packed into an attractive user-friendly dash.
But we’re not here for the bells and whistles. We weren’t initially impressed with the CR-Z’s handling. Although designed with sporty lines, and peppy character, for a Hybrid, the CR-Z didn’t shine in the twisty stuff.

So we got to work. First came a few basic measurements to give us an idea of what we had to work with.
The CR-Z is not particularly complicated as far as suspension goes. It has a conventional strut assembly up front and a torque beam shock/spring combo in the rear, much like it’s Insight predecessor, which we had recently converted.
Our biggest challenge was retaining travel while lowering the car. We found the tires relationship to the wheel well to be the limiting factor. We could only go so low before these two got together, but we went for it anyway (as always!).
The CR-Z was actually much lighter than we expected weighting in at a svelte 2800 pounds. This is good for two reasons; we don’t have to throw huge spring rates on to support it appropriately, and the lower rates won’t overwhelm the stock dampers, as there aren’t any performance aftermarket replacements available yet.

During the two days we spent on the engineering and install, we drove the CR-Z with a variety of rate combinations over a variety of roads, and eventually came to a combination complimenting the CR-Z’s sporty character.
The verdict, awesome! The CR-Z sits lower, handles better, and the owner has had nothing but good things to say about his “new” ride!
